# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the manufacture of glass (notified under document C(2012) 865) (Text with EEA relevance) (2012/134/EU), Division 18

Extent: E+W+S+N.I.

When nitrates are used in the batch formulation and/or special oxidising combustion conditions are required in the melting furnace for ensuring the quality of the final product, BAT is to reduce NOX emissions by minimising the use of these raw materials, in combination with primary or secondary techniques
The BAT-AELs are set out in Table 7.
If nitrates are used in the batch formulation for short campaigns or for melting furnaces with a capacity of < 100 t/day, the BAT-AEL is set out in Table 8.
A description of the techniques is given in Section 1.10.2.
Technique
Applicability
Primary techniques:
Minimising the use of nitrates in the batch formulation
The use of nitrates is applied for very high quality products (i.e. flacconage, perfume bottles and cosmetic containers).
Effective alternative materials are sulphates, arsenic oxides, cerium oxide.
The application of process modifications (e.g. special oxidising combustion conditions) represents an alternative to the use of nitrates
The substitution of nitrates in the batch formulation may be limited by the high costs and/or higher environmental impact of the alternative materials
Table 8
BAT-AEL for NOX emissions from the melting furnace in the container glass sector, when nitrates are used in the batch formulation and/or special oxidising combustion conditions in cases of short campaigns or for melting furnaces with a capacity of < 100 t/day
The conversion factor reported in Table 2 for specific cases (3 × 10–3) has been applied.
